Harris, entering his third season, started at both safety positions with the Bears and had five interceptions in the past two seasons. Harris also had an interception in the Bears' loss to Indianapolis in the Super Bowl.

"According to our scouts and coaches he's an instinctive player, and we feel he can come in here and compete," Panthers general manager Marty Hurney said.

Harris will likely step in right away as the starter at strong safety next to veteran Mike Minter. Nate Salley had been working with the first team until having a right knee injury in practice yesterday. Salley sat out practice today and is listed day to day.

The Bears have depth at the position, making Harris expendable.

"I think we're fortunate the Bears have a real surplus at that position," Hurney said. "Chris is a guy that we feel can come in here, compete and help us."
